Incidentally the Iheart Music Festival did take place in September and was originally going to be released on the CW this week though. It Turns out IheartRadio Productions happened to be in the same location the weekend before mass shooting took place. CW Reps said it was out of respect for the Mass Shooting Victims in Vegas.
Iheart is stating that they had filmed events that took place across the street from Mandalay Bay Hotel at a concert lot. Yes its the same exact concert lot that was the scene of the largest mass shooting in Nevada History and 1 week prior to the mass shooting.
